Problems solved by technology

However, no matter what kind of measurement method is used, it is impossible to fairly obtain the real electricity consumption cost of the user.
The more accurate method is to install a flowmeter and calculate the cost based on the flow of ice water passing through the flowmeter. This method is more expensive, prone to failure, and more troublesome to replace. The main reason is the physical characteristics of the refrigerant. Make the flowmeter unable to accurately calculate the flow of refrigerant

Embodiment 1

[0031] see figure 2 , figure 2 Disclosed is the connection relationship of a central air conditioner with multiple outdoor units and multiple internal units using the household metering system for the central air conditioner. An external unit composed of multiple external units is respectively connected to multiple units through multiple external unit adapter plates. A communication module is connected to the signal access point between the external unit adapter board and the internal unit.

Embodiment 2

[0033] see image 3 , image 3 Disclosed is the connection relationship of the central air conditioner with one outdoor unit and one inner unit, applying the household metering system of the central air conditioner. The difference between this embodiment and the first embodiment is that the metering system calculates the electricity consumption cost of an external unit and an internal unit, and no external unit adapter board is needed. A communication module is connected to the signal access point between the outdoor unit and the inner unit.

[0034] The principle of household metering method for central air conditioning:

[0035] Central air conditioners generally include at least one outdoor unit and multiple indoor units. Several indoor units are divided into groups, and one outdoor unit is used. The number of indoor units used by each user is variable. The user's air-conditioning fee includes the cost of using the outdoor unit and the cost of using the indoor unit. The ...

Abstract

The invention discloses a kind of method of central air condition individual measurement and a central air condition individual measurement system adopting the method and apportions the demand for electricity of the outer machine and the other electricity consumption indoor beside the insider machine to every insider machine. The measurement system includes at least a communication modular, a converter, a quantity of electricity display device and a processing device; one end of the communication modular connects into a air condition unit correspondingly and the other end of it connects to the processing device by the converter and the quantity of electricity display device connects to the air condition unit. One side balances the power consumption and on the other hand compute the practice consumption for the air condition in order to assurance the fair and reasonable according to the air condition's self ability, running pattern, the fan power, the ambient temperature and so on the series behaviors which makes a difference on energy consumption of the air condition.

Description

technical field [0001] The invention relates to the field of metering of air conditioners, in particular to a household metering method for central air conditioners. Background technique [0002] The central air conditioner is favored by more and more users because of its superior performance, but the characteristic of the multi-connection unit is that multiple indoor units with different capabilities share one outdoor unit, so how to fairly and reasonably consume each indoor unit It becomes a difficult problem to calculate the actual operating cost. The early measurement method was calculated by population, and gradually developed to apportion public electricity charges by construction area or by the number of households. However, no matter what kind of measurement method is adopted, it is impossible to fairly obtain the real electricity consumption cost of the user. The more accurate method is to install a flowmeter and calculate the cost based on the flow of ice water ...
